Way to go! Dr Lang says women should drink about half their body weight in water every day. For me, that translates into about 11 8 oz. glasses. And, if you drink coffee, you need to drink just as much water to counteract the caffeine, and you can't count it towards your water intake. That means, given that I drink about 24 oz of coffee every morning, I should drink 14 glasses of water. Wow. Drink up! And buy lots of toilet paper. LOL.
